To all whom it may concern:

Be it known that we, FREDERICK VVILLIAM KNOWLES and Gnonon TVILLIAMINDIAN, residing at The Glass Bottle Vorks, Thornhill Lees, nearDewsbury, in the county of York, England, have invented certain new anduseful Improvements in Machines for Mannfacturing Glass Bottles, Jars,and the Like; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to Which it appertains to make and use thesame.

This invention relates to machines for manufacturing glass bottles,jars, and the like, of the type in which a bracket carries the finishingmold unden the turnover motion, a finishing mold being provided for eachparison. In these machines, the paddling motion has usually been placedbehind the finishing mold, and the bracket which held the finishing moldwas pulled forward toward the workman to make room for the paddlingmotion, in operating which the workman had to come close to the hotmold.

Now according to our invention, the paddling motion is placed in frontof the finishing mold, and the bracket is pushed backward underneath theturnover motion while the paddling motion is in use. In order to allowthe open parts of the parison mold to clear the top of the finishingmold when turning over to receive the next charge, with the finishingmold in the position denoted, the framework of the turnover motion islengthened, so that the parison when turned up is in front of thefinishing mold, instead of behind it; and the bars which are linked atthe back to the piston of the air cylinder, and at the front to thepivoted halves of the parison mold, are for the same reason made crankedinstead of straight. Such machines as at present constructed are usuallyarranged with a single set of molds, or two sets back to back, or threeor more sets of molds and turnover motions radiating from a centralpillar; but we preferably place two, four, or other number of sets inparallel or side by side upon a movable carriage, or in a row upon abench or the like. By this arrangement both space and labor areeconomized, as each set of molds with its appurtenances only occupies asmall space in front of the furnace, say of 2 feet in Width by 2-3; feetin depth, and the waste of time and energy entailed by the rotary systemis avoided, so that three men (one at the back and two at the front) canwork four sets of molds, instead of three sets of molds as usual.

Our invention also comprises further improvements of detail as hereinset forth and claimed.

In the accompanying drawings :Figure 1 is a side elevation of a machineconstructed according to our invention. Fig. 2. is a front elevation andFig. 8 is a plan showing the arrangement of four such machines upon amovable carriage. Fig. 4 is a sectional plan on an enlarged scale,showing the plunger or neck core mold, and the means for opening andclosing the ring-mold or outer neckmold.

Letters a b 0 (Z indicate a set of four machines mounted upon a movablecarriage e. The two outer machines a and (Z are represented in outlineonly.

Fig. 1 may conveniently be taken to correspond with the machine 6 inFigs. 2 and 3, in which the parison is up and both molds closed, whilein the machine a in Figs. 2 and 3 the parison is down and both moldsopen.

On the bed f of the machine are guides in which slides the saddle orbracket it carrying the finishing mold 2' and paddle 7'. The stem of thepaddle j is connected by a link at to an eccentric or cam n pivoted atp, and actuated by a handle 9 By pressing this handle 9 downward and tothe left side, the cam n is turned about its center or fulcrum p, andcauses the link at to raise the paddle j; and on the said handle beingreleased, the paddle returns by gravity to its normal position.

On the pedestal a of the finishing mold are two studs 8, between whichis engaged a lever arm t actuated by the handle 21 to move the pedestalr and bracket h backward or forward; adjustable stops to limit thesemovements.

Letter 00 indicates the framework of the turnover motion, carrying theparison mold y, the plunger cylinder 2 and the air cylinder 1. The airis supplied at 2, entering the air cylinder through a valve at 3, andthe plunger cylinder through the curved pipe 4 controlled by the handle5. The parison mold is, as usual, opened and closed by means of the arms6 actuated by the piston of the air cylinder 1, the cranked form ofthese arms 6 being clearly shown in plan The plunger or neck core mold 7fits closely Within its cylinder 2, and to give pasage to the air, anumber of grooves or flutings 8 (Fig. 4) are formed in the saidcylinder, so that the air is evenly delivered all around the plunger,and at the same time the plunger is kept concentric with the cylinder,and thereby with the bottle or jar. The plunger is provided at its rearor upper end with two pins 9, 10, which rest upon semicircular inclinedor upwardly curved surfaces formed upon a collar 11 working upon thecylinder 2. This collar or double cam 11 being partially rotated by themovement to the left of the handle 12, the wedge action of its camsurfaces upon the pins 9, 10, causes the plunger to rise out of thebottle neck. The spiral spring 13 returns the plunger to its normalpositlon when the handle 12 is released.

The two halves 14, 15, of the ring mold or outer neck mold are eachcarried by a slide, these slides, 16, 17, (Fig. 4) being linked to acollar or boss 18 surrounding the plunger cylinder 2. As will beobvious, a movement of the handle 19 in the direction of the arrow seenin Fig. 1 causes the slides to recede from each other, and the ring moldis thus opened; while on the release of such handle the pull of thesprings 20, 21, causes the slides l6, 17, to approach each other, andthus closes the mold.

Liquid metal having been in the usual way poured into the closed parisonmold y, this mold is turned over by means of the handles 22, 23 or 24;,the parison mold opened by the cranked arms 6, the plunger lifted out ofthe bottle neck by means of the handle 12, the paddle actuated by thehandle (I is caused to rise and gently strike the underside of thependent mass of metal, the finishing mold z' is drawn forward by thehandle '0, closed upon the pendent metal by the handles 25, 26, lockedby the handle 27, the air handle 5 actuated to admit air through theplunger cylinder" .2 to blow the bottle, the ring mold opened by thehandle 19, releasing the bottle, the mold i pushed back by the handle a,unlocked and opened, when the finished bottle can be taken out of themachine.

l/Ve claim as our invention 1. In a bottle-machine, the combination,with a main frame provided with a horizon tal guide extending from backto front in the frame, of a slide movable in the said guide, a finishingmold secured to the said slide, a vertically slidable paddle carried bythe said slide at the front part of the machine and in front of the saidfinishing mold,

a reversible parison mold, said paddle and finishlng mold being slidableback and forth under the parison mold, and a frame connecting theparison mold with the main frame and extending horizontally over thefinishing mold when the paddle is directly under the parison mold.

2. In a bottle-machine, the combination, with a plunger cylinderprovided with an inlet pipe for compressed air and having a series oflongitudinal inlet grooves for air extending around it, of a plungerslidable in the grooved portion of the cylinder, a collar journaled 011the said cylinder and provided with a means for oscillating it, an outerneck mold formed in halves and mounted on slides, and links pivotallyconnecting the said slides with the said collar.

In testimony whereof we affix our signatures, in presence of twowitnesses.
